alsa-mixer: Add "Front Line Out" and "Rear Line Out"

"Front Line Out" was found in the wild on one of the machines we enable.
I figured I could just as well add "Rear Line Out" too, because that's
just as likely to show up.

As a reminder, "Front Line Out" means "a line out jack physically located
on the front side", where as "Line Out Front" means "a line out jack
playing back front left and front right channels in a channel map".
